Rice Jr. recorded 11 receptions, including a touchdown, during his senior season at UNLV. He spent his first three collegiate campaigns at UCLA after being recruited to Stanford by Jim Harbaugh.

The 49ers coach said he was impressed with the 5-foot-11, 185-pound pass-catcher when he ran the 40-yard dash and participated in other on-field drills during San Francisco’s local pro day on April 26.

“I’m trying to get in the door, front door, side window, I’m trying to jump in there,” Rice Jr. said that day, adding that he trains with his dad and that they share precise route-running and dependable hands. “All I want is an opportunity, so that’s what I’m working for right now.”

Last week, Rice Jr. tried out at the Baltimore Ravens rookie minicamp, yielding more praise from another Harbaugh.

"Jerry Rice Jr. has done a nice job," Ravens coach John Harbaugh told The Baltimore Sun. "He's a really good athlete. He doesn't have his dad's size, but he sure got his athleticism. He runs in a real similar way. He's got that West Coast offense down. He's probably had that playbook since he was in the cradle.

"He knows all the rules of the crossing routes. He knows what to do, very good hands, real smooth athlete. He did a real nice job."
